HELP ASAP!!
Alecsey [184]
The common difference equals:
10 (as 14-4=10, 24-14=10…)

The explicit formula of this sequence is:
Because Tn=4+(n-1)•10
T1=4+(1-1)•10=4
T2=4+(2-1)•10=14
.
.
.
Therefore T8=4+(8-1)•10=74

So the answer is the second option:)

The formula f 5280m can be used to convert a measurement of f feet to an equivalent measurement of m miles. If an airplane flies
konstantin123 [22]
Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.

So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:

f = 5280m => m = f / 5280

m = 21,120 / 5280 = 4 miles

Answer: 4 miles

Mallory needs to go to the airport. It takes her 120 minutes to get there by car. This is 3 times the time it takes by
seraphim [82]

It will take Mallory 40 minutes to get to the airport by train.

Step-by-step explanation:

Given,

Time taken by car = 120 minutes

Time taken by train = t

According to given statement;

Time taken by car = 3 times time taken by train

120=3t

Dividing both sides by 3

\frac{120}{3}=\frac{3t}{3}\\40=t\\t=40

It will take Mallory 40 minutes to get to the airport by train.
